Homework: Ch 11 HW: Two Sample Procedure HW Score: 21 _74%, of Question 5, 11.2.7.T 17 points Part 2 of 9 Points . ofl Save The following data represent the muzzle velocity (in teet per second) ot rounds fired from a 155-mm gum For each round, two measurements ot the velocity were recorded using two different measuring devices, resulting in the following data. Complete parts (a) through (d) below. Observation 793.1 802.7 2 790.4 790.3 3 794.7 797.4 4 793.7 7925 5 794.4 801 6 793.7 791.1 (a) Why are these matched-pairs data? The same round was fired in every trial All the measurements came trom rounds fired trom the same gun. Two measurements (A and 3) are taken on the same round. The measurements (A and B) are taken by the same instrument (b) Is there a difference in the measurement ot the muzzle velocity between device A and device B at the COI level of significance? Note normal probability plot and boxplot ot the data indicate that the differences are approximately normally distributed with no outliers. Let di = Ai- Identity the null and alternative hypotheses.
